Favicon Preview Tool
Before you ship a favicon, preview it at every standard size — 16, 32, 48, 64, 128, 256 — and against light and dark themes.
What looks great at 512×512 often loses readability at 16×16. The preview tool shows every size side-by-side so you can catch fuzzy edges before they're public.
We also simulate light and dark browser chrome, so you can spot themes where your icon disappears.
